Definitions
- the invention relates to a camshaft adjuster for an internal combustion engine with a housing according to the closer defined in the preamble of claim 1.
- the invention further relates to a method for producing a housing for a camshaft adjuster for an internal combustion engine according to the preamble of claim 10.
- a generic camshaft adjuster and a corresponding method for producing the housing thereof are known from DE 101 48 687 A1.
- the housing and / or the rotor is extruded, i. produced by extruding an aluminum alloy.
- camshaft adjusters and methods for their production are described, for example, in DE 199 55 507 A1, DE 198 17 319 C2 or WO 00/52308 A1.
- the housings of these camshaft adjusters can be designed, for example, as sintered, forged or cast parts. In any case, however, this requires a relatively high effort in the production of these camshaft adjuster.
- Another disadvantage of the known solutions is their usually very high Weight and the sometimes expensive installation of the individual sections of the housing.
- the jacket section of the housing is formed by a lengthwise profile section drawn from a tube as semifinished product, this results in an extremely lightweight housing for a camshaft adjuster.
- the method according to the invention can be carried out in a very simple manner, the inner contour of the shell section being given such dimensional stability and surface roughness by the drawing process that no further processing of the housing is required. After drawing, only a cutting of the tube to the length required for the housing of the shell portion is necessary. Overall, thus advantageously results in a very kos ⁇ ten enroller camshaft adjuster.
- a so-called vane rotor can be accommodated in the housing of the camshaft adjuster according to the invention if the jacket section has at least two bulges.
- both the jacket section of the housing and the rotor arranged therein can be constructed independently of the connecting elements used to connect the two cover sections.
- the connecting elements can ternatively outside or inside the shell section ver ⁇ run.
- FIG. 1 shows a side view of the camshaft adjuster according to the invention
- Figure 2 is a section along the line II-II of Fig. 1.
- FIG 3 shows a step in a method for producing a housing for the camshaft adjuster according to the invention.
- the camshaft adjuster 1 shows a schematic representation of a camshaft adjuster 1, which is provided for adjusting the angular position of a camshaft 2 with respect to a crankshaft, not shown, of an internal combustion engine, likewise not shown.
- the camshaft adjuster 1 may be formed, for example, in a form as described in DE 199 55 507 A1 or DE 198 17 319 C2 and therefore not explained in detail below.
- the clamping of the camshaft adjuster 1 on the camshaft 2 can take place by means of a central screw (not shown).
- the camshaft adjuster 1 has a housing 3, which in turn has two lateral cover sections 4 and 5 and a middle cover section 6 arranged between the cover sections 4 and 5.
- the cover section 4 facing the camshaft 2 is provided with a sprocket 7, which enables the integration of the camshaft adjuster 1 into a chain drive of the internal combustion engine.
- the two cover sections 4 and 5 are connected to one another by means of a plurality of connecting elements 8 extending beyond the jacket section 6, in the present case designed as screws, in order to be able to seal the housing 3 tightly.
- the connecting elements 8 could also run within the jacket section 6.
- the jacket section 6 is profiled in cross-section and, in the present case, has three bulges 9, so that it is suitable for a rotor 10 formed, for example, as a sintered or forged part with three To pick up wings 11. If appropriate, the rotor 10 could also have a different number of wings 11, for example two or four.
- the jacket section 6 would then have to be provided with a corresponding number of bulges 9. 2 it can further be seen that at least one of the bulges 9, in the present case two, is designed such that together with one of the vanes 11 of the rotor 10 it forms a chamber 12 for hydraulic fluid. Due to the subsequently described method for producing the jacket section 6, the wall thereof runs obliquely in this area, i. at an angle relative to the wing 11.
- the connecting elements 8 are each arranged directly adjacent to the bulges 9, wherein each bulge 9 is assigned in each case two connecting elements 8.
- the jacket section 6 is formed by a cut from a tube 13 as a semi-finished cut profile section.
- a seamless drawn pipe and a welded pipe can be used as semifinished product for the casing section 6.
- steel is used as the material for the tube 13, since this can have a sufficient strength with a relatively small wall thickness and thus allows a small overall size.
- FIG. 3 shows, in a very schematic representation, the step of producing the jacket section 6 from the initially round tube 13, wherein the tube 13 is pulled cold by means of a mandrel 14 arranged inside it and a die 15 surrounding the tube 13.
- the separation or cutting to length of the shell section S 1 to obtain its desired length can be done after drawing, for example by laser cutting, water jet cutting, sawing, grinding or another suitable machining method. If necessary, it is also possible to bring the shell portion 6 with an additional process step to the desired length.
